Firstly, thank-you for taking the time to read this.
I have an Xbox LIVE account under than gamertag of, "SGT Hennell". Until recently the error code 8015D003 popped up.I typed in the correct e-mail and password for it and comes up with, "Sorry, something went wrong with your Microsoft account. Go to https://Account.live.com for help. Code: 8015D003". Now, the e-mail that I signed up to Xbox LIVE with has been blocked and I've known this for a while but didn't care till now. Because I made this e-mail in 2006 when I was just a kid, I can't remember the information I used to sign up (i.e Birth date, security questions, my old phone number, etc). So when I try to complete the account recovery form on the PC, It sends me an e-mail to my other e-mail account and says I was unsuccessful in unblocking the account.
So, I was wondering if I could change the e-mail address for the blocked Xbox LIVE account without the log in details. Or is there any alternative I could do. Please help me!
